TAS3002PFBR

Audio Special Purpose Overview

The TAS3002PFBR is a stereo audio signal processor and system-on-a-chip by Texas Instruments, housed in a 48-TQFP (7x7) package. It integrates a 24-bit stereo codec with two I2C-selectable single-ended analog inputs per channel. The device performs digital parametric equalization, dynamic range compression, loudness contouring, and soft volume control via an I2C interface. It supports serial audio data formats including I2S, left-justified, and right-justified at 16, 18, 20, or 24 bits. Operating on a single 3.3V supply, it functions within a temperature range of 0°C to 70°C.

Audio Special Purpose Feature Summary

• Integrated 24-bit stereo ADC and DAC with programmable seven-band parametric equalization
• Supports I2S, left-justified, and right-justified serial interfaces for 16/18/20/24-bit data
• Features programmable dynamic range compression/expansion (DRCE) and loudness contour algorithms
• Includes six general-purpose input terminals for hardware control of volume, bass, treble, and mute

Audio Special Purpose Applications

• Digital speakers and active loudspeaker systems
• TV sets requiring commercial killer functionality and dynamic range management
• Headphone amplifiers utilizing the AllPass bypass mode
• Subwoofer and center channel processing via L+R monaural mixing

Audio Special Purpose Procurement Notes

Verify that the 'PFBR' suffix corresponds to the Tape & Reel packaging configuration as indicated in local product fields. Confirm the component meets RoHS3 specifications and check current availability status, as this part number may be subject to discontinuation or limited stock conditions.

Audio Special Purpose Selection Notes

Select this component when a single-chip solution for digital audio processing and conversion is required. Ensure the design accommodates a 3.3V power supply and utilizes an I2C controller for parameter uploads. Verify compatibility with the target sampling rates of 32 kHz, 44.1 kHz, or 48 kHz and the specific serial interface protocol used by the host system.

Audio Special Purpose Part Context

This device belongs to the TAS300 series of audio signal processors. It serves as a system-on-a-chip replacement for conventional analog equalization circuits. The TAS3002 specifically targets applications needing integrated digital filtering, tone control, and codec capabilities in a compact surface-mount package.
